Termination w.r.t. Q of the following Term Rewriting System could not be shown:
Q restricted rewrite system:
The TRS R consists of the following rules:
a(x1) → x1
a(x1) → b(c(x1))
b(b(x1)) → a(a(x1))
c(c(c(x1))) → b(x1)

Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
A(x1) → B(c(x1))
B(b(x1)) → A(x1)
C(c(c(x1))) → B(x1)
A(x1) → C(x1)
B(b(x1)) → A(a(x1))
The TRS R consists of the following rules:
a(x1) → x1
a(x1) → b(c(x1))
b(b(x1)) → a(a(x1))
c(c(c(x1))) → b(x1)
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
